We present a novel multi-emitter electrospray ionization interface for the coupling of microfluidic
free-flow electrophoresis (μFFE) with mass spectrometry. 15 sample streams coming from 15 μFFE outlets were continuously analyzed in quick succession to monitor the electrophoretic
separation in the microchip.
